With these two functions 1) tan(2)=tan(2)cos 2) sin(2X)=sin(2)sin

Prove that you get as a final answer cos(2)=cos(2)cos(2X)

y Ellipticity angle Rotation angle Polarization ellipse Figure 1 Polarization ellipse in the Xy plane with the wave traveling in the zdirection (out of the page). The length of the polarization ellipse is given by 2a: and the width by Ban. The shape of the ellipse and its handedness are characterized by the ellipticig' angle 37 , which is dened as where the plus sign corresponds to lefthanded polarization {LHP} and the minus sign to right handed polarization {RHP}; Z is bounded within the range ;r/ 4 5 Z s :r/ 4 ( z = l for linear and 2' = :Ir/at for circular). The quantity R = an fag. is called the axial ratio of the polarization ellipse: Ris bounded within the range 13 R 0 if c055 )v0 and y 0 if sin' >0 (and vice versa) denotes LHP while I
